"Canada is the largest export market for the U.S. and makes up one of the smallest trade deficits, owing largely to U.S. demand for energy-related products.
Trade in the auto sector is balanced between the 2 nations. While President Trump has mused that the U.S. could replace Canadian auto exports with its own domestic supply, the highly integrated North American supply chains is a major complicating factor.
Flipping this argument on its head, Canadian auto manufacturing has room to expand. Canada produces only 14 car models but consumes 325 models. The U.S. produces 121 models of the 328 models consumed by Americans.
With respect to Trump’s assertion that the U.S. subsidizes Canada to the tune of US$200 billion per year, it’s unclear where this number is derived. In any event, rather than a subsidy, the U.S. trade deficit is a by-product of U.S. economic outperformance relative to other countries."
